COUPLING.

SPECIFICATION forming part ofV Letters Patent No. 630,882, dated August15, 1899.

Application filed April 29, 1898. Serial No. 679,267. (No model.)

To all whom t may concern:

Be it known that I, EU GEN HABER, a subject of the Emperor ofAustria-Hungary, residing at Vienna, Empire of Austria-Hungary, haveinvented certain new and useful Improvements in Couplings, of which thefollowing is a full, clear, and exact specification.

The present invention relates to a couplingclutch; and it consists ofthe details of construction hereinafter set forth, and particularlypointed out in the claim.

In order to render the present specification more easily intelligible,reference is had to the accompanying drawings, in which similar lettersof reference denote similar parts throughout both the views.

Figure l is an elevation of the clutch; and Fig. 2, a verticalcross-section through the same on line ,r a5, Fig. l.

The two shafts a and h are mounted concentrically, the crank-arm n beingkeyed to h and the disk M, having cylindrical rim, being keyed fast toa. W'ithin the disk-rim a crossbarm is mounted and connected by a slotto the pin n of the crank-arm n, the said bar having mounted pivotallyat either end the friction blocks o1' shoes m' m2, adapted to contactwith the interior surface of the rim of the disk M.

The operation of the device is such that the two shafts ci and b will becoupled thereby in any case-. e., it is a matter of indierence which ofthe two shafts is the driven shaft. If b is the driven shaft in thedirection of the arrow 2, the pin n' will force the bar fm, and with itthe friction-blocks m m2, against the rim of the disk M and effect thecoupling, and if the disk M is driven in the direction of the arrow lthe friction-coupling between the riln and the friction-shoes will alsobe eected, and the shaft h will be operated from the disk M.

l claim as my invention- A double-acting friction-coupling, consistingof two concentrically-mounted shafts a and b, a crank-arm fast on one ofsaid shafts and a disk having suitable rim fast on the other, shoesadapted to contact and form a friction-coupling with the said disk-rim,said shoes being connected pivotally to a rigid bar having apin-and-slot connection with the end of the crank-arm in the manner andfor the purpose substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

EUGEN HABER.
